Abstract

According to a cold / hot water supply apparatus of the present invention, when a cooling operation mode in which fluid which flows out from a first heat exchanger 22 absorbs heat in a third heat exchanger 53 is switched to a heat-accumulation operation mode in which fluid which flows out from a first heat exchanger 22 heats water in a heat accumulator tank 55, it is determined whether fluid which flows out from the first heat exchanger 22 should be made to flow to the heat accumulator tank 55 or to return to the first heat exchanger 22 without through the heat accumulator tank 55. According to this configuration, heating time of the heat accumulator tank 55 can be shortened, and energy efficiency can be enhanced.

Description

technical field

[0001] The present invention relates to a hot and cold water supply device that uses a heat pump to store heat in cooling and heating equipment and heat storage tanks in indoor spaces. Background technique

[0002] Conventionally, there is known a hot and cold water supply device including a cooling operation mode for cooling an indoor space and a heat storage operation mode for heating a heat storage tank (for example, refer to Patent Document 1).

[0003] Figure 6 Shown is a refrigeration cycle device 100 for cooling and heating an indoor space and storing heat in a heat storage tank 300 . In the refrigeration cycle device 100, the refrigerant circuit 110 for circulating the refrigerant, the compressor 111, the four-way valve 112, the first heat exchanger 113, the expansion member 114, and the air-to-fluid heat exchanger 115 are connected in a ring shape by piping. .

[0004] The first heat exchanger 113 includes a refrigerant circuit 110 and a fluid cir...
